Legumes and animal manures are the primary sources of nitrogen and phosphorus for organic farmers. Balancing these two nutrients, however, is more challenging for organic than conventional farmers since animal manures have a predetermined nitrogen to phosphorus ratio and nitrogen inputs from legumes can be quite variable. I will discuss results from field experiments conducted in Maryland to improve management of legumes and animal manures in concert for short-term efficacy and long-term sustainability.
